摘　　要：光生态膜无雾滴、透光度好、能提高棚内温度、可将太阳光谱中作物不能吸收的绿光转变为作物可利用的红光和蓝光。对其进行光能利用率试验研究表明:光生态膜在水稻育苗上应用可提高水稻秧苗素质、产量和经济效益,是水稻育苗的一种新型棚膜。Light-ecological film is a new type film. With characters of fogdrop-proof and good translucidus quality, light-ecological film can improve the utilization rate by transforming the green light that can't be absorbed into red and blue light which can be utilized by crops, which contribute to improving the temperature in plastic greenhouse. The experiment shows that the application of light-ecological film to raise seedlings in paddy can improve seedlings quality, yield and economic benefit.
